Zhuzuigu (Pinyin: Zhū zuǐ gǔ) is a Zhuang nationality musical instrument. Named because the drum is shaped like a pig's mouth. It is popular in Xincheng County in the central part of Guangxi Zhuang Autonomous Region. When playing, the drum is placed on a wooden frame and played with a double chime, with a high-pitched and sharp sound. It is used for the accompaniment of Zhuang silk string opera, like the bangu in the Peking Opera band.
